【摘要】 丁烯酸乙烯酯存在于醋酸乙烯酯生产的工业废液中,可用蒸馏法提取及纯化,具有一些独特的性质:如在一定条件下会聚合形成环状结构;用于以聚醋酸乙烯酯为基础的乳胶漆交联改性时,无须引发剂和加热,只是简单混合即可使耐洗刷次数增加几倍,还可与其它乙烯基酯、氯乙烯、苯乙烯、马来酸酐等多种单体共聚,主要起提供交联的作用。更多还原

【Abstract】 Vinyl crotonate existed in the industrial waste liquid of vinyl acetate production, and was not difficult to extracted and purified. Vinyl crotonate had some special properties. e. g., it could be polymerized into a ring structure under certain polymerization conditions. When it was used for crosslinking modification of emulsion coatings which were based on poly(vinyl acetate), there was not a need for initiator and heating. Vinyl crotonate could copolymerize with vinyl esters such as vinyl acetate, and a variety of monomers such as vinyl chloride, styrene and maleic anhydride. It mainly acted as a crosslinking donor.更多还原
